A cold planer, comprising:

• a frame;
• a platform structured and arranged on the frame;
• an operator station structured and arranged on the frame;
• a ladder including a first end and a second end, the first end being coupled to a base portion of the frame, the second end being coupled to a cab access portion of the frame;
• a platform and stair illumination device adapted to illuminate the platform and the ladder;
• an operator-station illumination device adapted to illuminate the operator station;
• a forward keypad, relative to the ladder, including a plurality of first control buttons, wherein each of the plurality of first control buttons is adapted to generate a first signal when actuated;
• a rearward keypad, relative to the ladder, including a plurality of second control button, wherein each of the plurality of second control buttons is adapted to generate a second signal when actuated;
• a timer;
• and
• a controller operatively connected to each of the forward keypad, the rearward keypad, and the timer, the controller being configured to:
• receive the first signal from one or more of the plurality of first control buttons of the forward keypad;
• receive the second signal from one or more of the plurality of second control buttons of the rearward keypad;
• activate the platform and stair illumination device and the operator-station illumination device upon a receipt of either of the first signal and the second signal;
• set the timer to a predetermined period of time;
• and
• deactivate the platform and stair illumination device and the operator-station illumination device when the predetermined period of time elapses.
